DRAFT-RIGGING.

Specification of Letters Patent.

Patented Mar. 9, 11215..

Application filed .Tune 24, 1913, Serial No. 775,557. Renewed October 8, 1914. Serial No. 865,778.

To all whom it may concern.-

Be it known that I, PERRY BROWN, a citizen of the United States of America, and a resident of Coraopolis, in the county of Allegheny and State of Pennsylvania, have invented. certain new and useful Improvements in Draft-Rigging, of which the following is a specification.

This invention relates to improvement in draft rigging for railway cars and the invention consists in the construction and arrangement of parts hereinafter described and then definitely pointed out by the claims at the end. hereof.

In the accompanying drawings: Figure 1 is an under side perspective View of my invention. Fig. 2 is a top plan view of the same with parts broken away. Fig. 3 is a side elevation with parts broken away. Fig. 4 is a longitudinal section. Fig. 5 is a cross section through the line 55 of Fig. 4. Fig. 6 is a perspective view of certain parts detached.

Referring now to the details of the drawings by numerals: 1 designates the usual or any desired form of end sill to which is secured a striking or face plate 2, through the vertical sides of which passes the shank 4 of the usual draw bar. A carry iron 6 may be passed through slots in the vertical members of the striking or face plate to support the draw bar, as indicated in Figs. 1 and 4.

The features so far described are not part of my present invention but are described in order to better illustrate my invention.

Secured to the end sill 1 are two longitudinal sills 8 and 10. Ordinarily, the parts of the draft rigging are supported by intermediate sills and to that end said sills are reinforced by cheek plates but in the present drawings, I am illustrating a construction which dispenses with the ordinary cheek plates. To this end, I form the sills 8 and 10 of especially rolled material of the shape shown in cross section in Fig. 5. It will there be seen that the parts of the sills 8 and 10 which support the draft rigging are made of much thicker material, as indicated at the places marked 12 and 14. The part of the sills above the thickened portions 12 and 14 is of the thickness usually employed for the intermediate sills. By making the portions 12 and 14 of much thicker mate rial, I am able, as above pointed out, to dispense with the usual cheek plates now com monly employed. To the shank of the draw bar is secured a socket piece 16, preferably a casting. This socket piece is formed of the shape shown in perspective view in Fig. 6 and in sectional view in Fig. 4. In order to receive the shank of the draw bar, the socket piece is formed with an opening designated by the numeral 20 and the shank 4 of the draw bar is inserted within the socket plece, transverse shoulders 22 passing into the opening 24 and abutting against the wall 26. A transverse shoulder 28 formed on the opposite side of the draw bar pro- ]ects downward, as shown in Fig. 4, and the socket piece is provided with horizontal slots 30 through which is passed 'a horizontal bar 32, this bar 32 abutting against the shoulder 28. This bar 32 therefore effectually locks the socket piece 16 to the shank of the draw bar. The horizontal bar also passes through elongated slots 40 and 42 formed in the thickened part 14 of the sills 8 and 10; the slots 42 being longer than the width of the bar 32 in order to permit the draw bar to move backward and forward between the sills 8 and 10. From the foregoing, it will be seen that the bar 32 therefore serves two functions; first, of locking the draw bar to the socket piece 16, and second, of passing through the sills 8 and 10 and therefore supporting both the socket piece and the shank of the draw bar. The socket piece is provided on its rear side with two apertures 44 and 46 through which are passed heads 48 and 50 of two bars 52 and 54 (see Fig. 6). The interior socket piece is formed with openings to receive the heads 48 and 50, as illustrated in Fig. 2. These bars 52 and 54 have their ends 48 and 50 inserted through the apertures 44 and 46, before the shank of the draw bar is inserted in the socket piece 16; and after the bars 50 and 54 are in place, the shank of the draw bar is inserted in the socket piece and when it is locked in position by the bar 32, the shank of the draw bar thereby effectually secures the heads 48 and 50 in their openings in the socket piece, as illustrated in Figs. 2 and 5. When the draft rigging is assembled, the aforesaid bars 52 and 54 project rearwardly from the draw bar shank and its socket piece, as illustrated in the drawings, and are adapted to support the springs or cushioning means as illustrated.

Immediately to the rear of the position normally occupied by the socket piece 16,

two slots are formed in each of the sills 8 and 10, the upper slots being directly over the under slots and the slots in one sill being in horizontal alinement with the slots in the other sill. I have designated the slots in the sill 8 by the numeral and the slots in the sill 10 by the numeral 62. Through these slots are passed two independent horizontal bars 64 and 66. The slots 60 and 62 are longer than the width of the bars in order that the bars may be moved to the rearward. Immediately behind the slots 60 and 62, and in alinement therewith, are additional slots and 7 2 through which are passed another pair of independent bars 74 and 76. These slots 70 and 72 are also longer than the width of their bars 74 and Z6, as illustrated in Fig. 1. Between the bars 64 and 66 and the bars 74 and 76 are placed the springs hereinbefole referred to, which in the normal position of the parts, act to hold the front bars 64 and 66 against he front end of th ir lots 60 nd 6 and the rear bars 74 and 76 against the rear ends of their slots 70 and 72. The aforesaid bars 52 and 54 have placed over them a rear vertically disposedplate 80 secured in position by means of nuts 82 and 84. The springs hereinbefore referred to which are between the bars 6466 and 74-76 may be of any desired construction but 1 much prefer the form illustrated in the drawing which consists of sets of duplex springs designated by the numerals 86 and 88. The inner springs 86 are longer than the outer springs 88 so that the first part of he ea is a ied n ely by th sma springs 86; and after the inner springs 86 have been partially compressed, further compression will be felt by both sets of springs.

The device, as I have so far described it, may be operated very effectually and it will be understood that upon an impact, the draw bar and its socket piece 16 are shoved to the rear, thus causing the socket piece to shove the horizontal bars 64 and 66 in their slots 60 and 62, thus compressing the springs between the two sets of bars, as h ba s 74 a 7 can t move far he t0 the rear. On a pull, the shank of the draw bar and its SOCket piece pull upon the bars 52 and 5 and these bars draw upon the Vertically disposed plate 80, thus moving forwardly the horizontal bars 74 and 76 in heir Slots 70 and .2 a d e e y compress the springs against the horizontal bars 64 and said ba s be g n w o fined by the front ends of the slots 60 and 62. In his. last m vement, hat is to say, on th P he d ew her and t s ck t p e e ar drawn away from the horizontalbars 64 and 66 but on the impact said parts, the draw bar, the socket'piece, and the horizontal bars 64 and 66 all travel together.

In addition to the two sets of springs 86 and 88 which are described as located between the sills 8 and 10, I also prefer to employ two additional sets of springs outside of the said sills 8 and 10, as clearly illustrated in Figs. 1, 2 and 5. To accommodate these springs, the duplex horizontal bars 6466 and 7476 are extended laterally on each side of the sills 8 and 10. Heavy bolts 90 and 92 are passed through the end sill 1, the ends of the bolts passing between the two sets of horizontal bars, and around said bolts are secured the additional springs 94 and 96 (see Fig. 2). Over the rear ends of the bolts 90 and 92 are slipped two heavy washers 98 and 100 which are secured in position by nuts 102 and lO-l. It follows from the foregoing construction that whenever the draw bar receives a shock, the duplex bars 64 and 66, as before described, compress the springs 94 and 96 against the duplex bars 74 and 76 in the same manner that they compress the interior springs 86 and 88 and likewise upon a pull, the rear duplex bars 74 and 76 compress the exterior springs 94 and 96 against the front duplex bars 64 and 66. The purpose of the bolts 90 and 92 is not only to form a support for the exterior springs 94 and 96 but also act to further reinforce the rest of the supporting devices since part of the impact is carried by these bolts 90 and 92, as the shock of the impact against the duplex bars 7 4 and 7 6 is not only carried by the rear walls of the slots 70 and 72 but also by the heavy washers 98 and 100 and their nuts 102 and 104. Each set of duplex bars 64.66 and 7476 may be yoked together by bolts 108 and 110.

It will be observed that the socket piece 16 is not connected to the duplex bars 64 and 66 but merely projects against the same. Therefore, upon a pull the draw bar and its socket piece pull away from the forward horizontal bars 64 and 66. The aforesaid bars 64 and 66 are afforded a very wide bearing in the sockets in the sills 8 and 10, and afford a very resilient means of backing up the draw bar and its socket piece, for, when the cars are taking a curve, the duplex bars 64 and 66 move to the rear at one end only, the other end acting on the fore-ends of the slot as a fulcrum. Therefore, the draw bar and its socket piece may adjust themselves as the curve requires. This movement is shown in dotted lines in Fig. 2 It follows from this construction that in taking a curve, the draw bar and its socket piece are freely moved backward at either side, with their duplex bars, indepeindently of any movement on the other s1 e.

From the foregoing and accompanying drawings, it will be seen that I have constructed a draft rigging of simple but very durable construction, and one in which practically all the parts, except the main socket piece 16, may be made of wrought material.
